72 Chevelle...350.....The ice in my engine expanded and cracked the water jacket inside the valley. The crack is an L shaped crack on both sides of the valley right above the no. 1 & 3, on one side, and the 2 & 4 spark plug on the other. I heard from a neighbor that I could drill a hole at each end of the crack to stop it from running, grind along the crack a little to make it easier to fill, and then fill it all in with JB weld for a quick fix that would let me buy some time to get a new block since this is mine and my wife's second car for work. He swears by it. I thought i'd get a second opinion before I waisted my time. What do you guys out there think???
